Abstract

PCT No. PCT/EP94/01102 Sec. 371 Date Oct. 13, 1995 Sec. 102(e) Date Oct. 13, 1995 PCT Filed Apr. 9, 1994 PCT Pub. No. WO94/24595 PCT Pub. Date Oct. 27, 1994An optical fiber cable, including optical fibers and a tube housing the fibers, is made by a process wherein optical fibers are fed from one or more pay-out device to the interior of an extrusion head which also receives a sheathing material in viscous form. The extrusion head extrudes the viscous material to form a sheath surrounding, but out of contact with the fibers. With the fibers still out of contact with the sheath, the fibers and sheath pass through a jig which calibrates the sheath to the final form of the tube, and cools the viscous material in a first stage of solidification. Thereafter, the cable comprising the tube and optical fibers is would up around a first draw-in device and heat treated. From the first draw-in device the cable passes to a second draw-in device with the tension of the cable between the two draw-in devices being regulated.
